ok to get to the point here i know 96-98 ex heads dont have FIA and 99-00 ex heads do, i have a 00 ex coupe and blew motor and picked up a 97 head. i am still using all my stock externals from my 00 motor ex: exhaust mani and intake manifold but 00 manifolds have holes for the FIA and the 97 heads do t have FIA therefore creating a leak and my idle to surge up n down. SO, the question is is there some thing i can do to the manifold to stop the FIA or disable it? any help would be appreciated.
